Tak an other smartphone (I took an iPhone 5) and send a contact via "message" from there to your Jolla phone.

You get a notification. Swipe from the bottom outside into the middke of the screen in order to get the event view.

Expected result: There is a notification for the new MMS containing an appropriate icon. The correct icon would be a small version of the contact icon used in the message view.
Current result: There is a notification for the new MMS containing an icon that looks like a play button and should be used for videos only.
